Abstract

With every new video coding standard the general rule of thumb has been to maintain same video quality at a reduced bit rate of about 50% as compared to the previous standard. H.265 is the latest video coding standard with support for encoding videos with wide range of resolutions, starting from low resolution to beyond High Definition i.e. 4k or 8k. H.265 also known as HEVC was preceded by H.264 which is very well established and widely used standard in industry and finds its applications in broadcast, storage, multimedia telephony. Currently almost all devices including low power handheld mobile devices have capabilities to decode H.264 encoded bitstream. HEVC achieves high coding efficiency at the cost of increased implementation complexity and not all devices have hardware powerful enough to process (decode) this HEVC bitstream. In order for HEVC coded content to be played on devices with support for H.264, transcoding of HEVC bitstream to H.264 bitstream is necessary. Different transcoding architectures will be investigated and an easy to implement scheme will be studied as part of this research.
